Diabetes is More Nurture Than Nature

A study of twins suggests that the development of insulin resistance, a precursor to adult-onset diabetes, is influenced more by current body weight than by birth weight.

Low birth weight has been linked to high insulin levels. But this relationship may occur strictly in the womb, and not in later life.

Investigators studied the between birth weight, body mass index (BMI), and insulin resistance in almost 1200 female twins. They failed to find any significant relationship between weight at birth and the development of insulin resistance. There was, however, a significant relationship between insulin resistance and current weight.

What Happens to Your Body Within an Hour of Drinking a Coke

Here’s just some of what happens when you drink a Coke:

Within the first 10 minutes, 10 teaspoons of sugar hit your system. This is 100 percent of your recommended daily intake, and the only reason you don’t vomit as a result of the overwhelming sweetness is because phosphoric acid cuts the flavor.

Within 20 minutes, your blood sugar spikes, and your liver responds to the resulting insulin burst by turning massive amounts of sugar into fat.

Within 40 minutes, caffeine absorption is complete; your pupils dilate, your blood pressure rises, and your livers dumps more sugar into your bloodstream.

After 60 minutes, you’ll start to have a sugar crash.

Are You a 'Cyberchondriac'?

Because of the Internet, many people have developed what used to be known as "medical student syndrome"; after getting some basic information, and little context, they self-diagnose in ways that can be far from the mark.

A sign of becoming a "cyberchondriac" may be that you feel worse after Web surfing instead of better.

Robin DiMatteo, a professor of psychology, says, "If research on the Internet helps to make you feel empowered, and engaged in a dialogue with your doctor, it's helpful.” By Dr. Vicki Rackner, surgeon and patient advocate, "If you feel more scared and confused after being on the computer for half an hour, that's not good."

If you quickly become convinced your shaking hands are Parkinson's disease, or your sore throat is an immune deficiency, you may need to back away from the computer for a while.
